* @assertion A generic type alias is a declaration [D] of one of the following
* forms:
* m typedef id<X1extendsB1, ..., Xs extendsBs> = T;
* ...
* where [m] is derived from metadata, [T] is a type, and [S?] is a type or the
* empty string.
* @description Checks that constant generic class constructor can be used as
* metadata, but generic metadata type argument cannot be used in metadata.
